Police first made contact with the boy's grandmother at the home in the 2900 block of Starview Lane after a call to police about a domestic incident. Judy Archer told police her grandson and her daughter Bonnie Emma Archer, 27, were in the basement at 9:43 p.m. when she suddenly heard the boy crying, court papers say.

Judy Archer rushed downstairs to find the boy lying on the basement floor, according to court records. She told police that when she questioned her daughter about what happened, the woman remained silent, court documents say. The boy allegedly told his grandmother that his mom had hit him and showed Judy Archer the broken bamboo torch he said Bonnie Archer used in the assault.

Police say the boy had a bloody lip, scratches and cuts on his wrists and lump on his head above his ear. When they questioned Bonnie Archer about her son's injuries, she said the boy spit at her so she smacked him in the face, according to authorities. Bonnie Archer allegedly had no answer to an officer's inquiries about the other injuries on the boy.

Police say the 4-year-old was sent to St. Luke's University Hospital in Fountain Hill for treatment of his injuries.

Bonnie Archer was arraigned before on-call District Judge Richard Yetter III on charges of aggravated assault, simple assault, endangering the welfare of a child and harassment. She was sent to Northampton County Prison in lieu of $25,000 bail. If Archer makes bail, she is prohibited from having any contact with her son until the case is resolved, according to Yetter's orders.
